Title: Guide member of veneer
Inventor: TAKAGI YUKIO
IPC: B27L5/02
Filed: 1993-06-11
Abstract: PURPOSE:To smoothly discharge a veneer even if a thickness of the veneer is altered by providing a member for constituting a part of a discharge route of a veneer at a rear side of the veneer, and adjustably providing an interval to a pricker corresponding to the thickness of the veneer. CONSTITUTION:When the thickness of a veneer is altered, a cam shaft 43 is so controlled to be rotated by a control circuit as to become an interval of prickers adapted for the thickness of the veneer. A cam 45 displaces a guide body by rotation of the shaft 43. Accordingly, problems in which a bottom 33a of the pricker compresses a surface of the veneer thereby to generate a compression damage in a riblike state and in which a compression amount is increased to make the discharge difficult to finally cause clogging of plates are eliminated. A protruding amount of the pricker to discharging veneer after the thickness of the veneer is altered is decided according to relative positional relationship between a position of an edge 33b of the pricker during cutting and a height of an end of the guide body.

Title: Track jumping controller
Inventor: NOGUCHI YOSHIHIRO
IPC: G11B7/085
Filed: 1990-06-26
Abstract: PURPOSE:To control track jump by generating a brake pulse without fail even when the generation of a zero-cross signal is made abnormal by dust or the like by generating the brake pulse by earlier one of the zero-cross signal and a timer signal. CONSTITUTION:When a seek jump command is inputted, a jump driving pulse generator 4 outputs a kick pulse and when the zero-cross signal or the timer signal from a timer 10 is inputted, the generator 4 outputs the brake pulse to control an actuator 11. Namely, when the seek jump command signal is inputted, the kick pulse is outputted as a jump driving pulse and the time 10 is operated as well. At such a time, when dust is stuck onto the track,the generation of the zero-cross signal is delayed for a track error signal. Therefore, the kick pulse returns to a zero point, the timer signal is generated, the brake pulse is generated and track jumping is normally executed. Thus, even when the tracking error signal is distrubed by dust or flaw, etc., the jumping operation of the track can be controller without fail.
